I am looking for advice/recommendations for the best cabling path on a 04 Outback. I have purchased a Redarc battery isolator, 10m of 6 b&s twin cable and 50 amp anderson plugs to provide charging on the move.

if you look at your alternator rating (normally written on the sticker on it) it will be someware between 50 and 100 amps 70 at a guess but i havent looked at the newer model outbacks

the cable and conectors will have to be rated for equal or greater than this
for 50amps your looking at 10mm2 cable 70a 25mm2 and 35mm2 for 100amps but the bigger the better

the redarc solonides are normally rated at 140amps or something

and your anderson conectors may be right if you dont flattern the traler battery too much

the most important thing is to use large cable and good conections to minimise voltage lost along the cable run and stop hot spots

Are you asking whether to run it under the body, or to pull the trim along the side of the car and run it beside the seats?

Its probably gonna be easier to run it under the car, but make sure you use double insulated cable, or run that corrugated trunking over it where is is likely to be damaged.

Always install a fuse close to the battery (in your case id have a fuse at each battery)

6GA will be fine but you can never go too big when trying to charge a remote battery.

Fuse both batteries right at the positive post for safety.

I would look at running the cabling under the trim down one side of the car. be sure to use split loom tube to protect the cable anywhere it is likely to wear.

Ive checked out these redarc solenoids on line. Here is what I use. http://www.ase-supply.com/Battery_Isola ... _s/153.htm
Pretty good value and mine has lasted 6 years so far. I use Anderson sb50 connectors and a circuit breaker. I charge 2 deep cycle 6v golf cart batteries that run a 2000w intermittant, 1000w continuous invertor, which is fused additionally with a buss ann-150 fuse. Wiring is alternator specific and this example is the configuration I use.

I've mounted the second battery in the car and am using a 12 pin trailer plug an socket mind you I always keep my fridge in the car, why pay $3 for a can of drink at a servo when you can buy it for $0.50 my fridge paid for itself in no time.

good for keeping the shopping cold on hte way home too

indeed it is when your going via Alice Springs!!!

i have same car ran my cables down left hand side of car on the inside very easy and the safest way to go, cables come through firewall just behind glove box then down under carpet basically following fuel lines through to back. grab rear seat at the front of it lift up and you will see how to get cables up to tyre well etc

Thank you for all your reply's it has been truly helpful. Now to find a spare minute to run the cable.
